REVERSIBLE SIGN.

SPECIFICATION forming part of Letters Patent No. 360,503, dated April 5, 1887. Application filed February 17, 1887. Serial No. Q J'LEJOR. (No model.)

To all whom it may concern:

Be it known that I, JOHN N. AKARMAN, a citizen of the United States, and a resident of Vere-ester, in the county of Worcester and State of Massachusetts, haveinvented newand useful Improvements in Reversible Signs and AdvertisingBoards for Street-Oars, of which the following, taken in connection with the accompanying drawings, is a specification.

Figure 1 represents a sectional side eleva tion of the invention. Fig. 2 represents an end view seen from X in Fig. 1. Fig. 3 represents an end view seen fromY in Fig. 1; and Fig. 4. represents a crosssection on the line A 13, shown in Fig. 1.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

a represents the board or sign, which may be fiat or three-sided, or with fourequal sides, according to the number of reversible sides required on the sign. To one end of the sign a is secured in a suitable manner the journal Z), of cylindrical section, which journal fits loosely in a cylindrical perforation, c, in the bearing 0, as shown. To the opposite end of the sign or board a is secured the cylindrical journal cl, resting loosely in the lower end of the slotted or forked opening e'in the bearing 6, as shown. In one piece with the journal (2'', or firmly secured to it, is a hub, d, having on its circumference two or more notches, d (l, as shown, and on the inside of the bearing 6 is arranged a locking tooth or projection, e, (shown in Figs. 1 and 4,)which latter is made to engage in one of the notches d when the sign is in use.

e is a pin or equivalent device passing through a perforation in the upper forked end of the bearing 6, so as to prevent the journal d from being accidentally disengaged from the bearing 0 when the sign a is being turned around its axis.

The sides of the sign are to be marked or lettered according to the uses for which they are intended, and when it is desired to change the side of the sign that is to be shown all that is necessary to do is to raise it a little in the end where the journal d is located sufficiently to disengage the projection c from the notch d, to which it was locked, and then turn the sign a around its axis a quarter or a third or half of a revolution, as may be desired, and allow it to drop by its own gravity, causingit to be locked and held in the desired place by the projection c and a notch, d, on the hub d.

If it is desired to remove the sign entirely from its bearings, all that is necessary to do is to remove the pin 0 from the upper end of the forked bearing 6, and to raise the journal (1 out of the slot 6, and then to slide the journal I) out of the perforation in the bearing 0, when another sign or board may be inserted and supported in the bearings c c.

This my improved reversible sign or board is especially adapted for the top of street-cars or other vehicles; but it is also equally useful for all other purposes where a reversible sign is needed.

, By the arrangement of the notched hub d d and stationary locking projection e, I am able to use a sign with more than two sides, three or four sides being preferable, and thus the capacity and use of it is increased or doubled as compared with other signs 110w in use. Another advantage of this construction is that if a two-sided sign is used it can be locked and held in a horizontal plane without showing any marks or lettering, as may be needed for various purposes.

WVhat I wish to secure by Letters Patent and claim is The sign or board a, having in one end the journal I), loosely mounted in a perforation in the bearing 0, and having in its other end the journal (1, vertically adjustable in the slotted bearing 0 c, said journal dhaving the huh (I, provided with peripheral notches or recesses d (1, adapted to lock on the stationary projection or tooth e on the bearing a, as and for purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence oftwo subscribing witnesses, on this 31st day of December, A. D. 1886.

JOHN AKARMAN.
